If you’ve been struggling with a patchy lawn all summer, the time to act is now.
On this Horticulture Day edition of Talk of Iowa, host Charity Nebbe talks with Iowa State University Extension turf grass specialist Adam Thoms about seeding, re-seeding, core aeration, and other late summer tasks.
Thoms says that Mid-August through mid-September is the ideal time to seed your lawn because the fall weather makes it hard for weeds to germinate.
"With the cooler nights, crabgrass is slowing down," Thoms says.
Before seeding, be sure to aerate using either a machine or handheld aerator. Then, between now and September 15th, Thoms recommends fertilizing your freshly seeded lawn to keep it well-nourished.
"The best defense against weeds is a healthy yard."
Later in the hour, Iowa State University Extension Horticulture Specialist Richard Jauron joins Thoms to answer listener questions.
